' Specification forming part of Letters Patent No` 39,514, dated August 1l, 1863.

, being had to the accompanying drawings, making a part of this specicatiomin which#- Figure l is. a side elevation. Fig. 2 isA a plan. Fig. 3 is a longitudinal vertical sec,- rion of my invention, as applied to the soles of boots or slices.

' Myinvention consists 4of fa combined .-heel iron and ice-calk, to be worn on thejsoles of boots and shoes, and so constructedasto furnish apermanent xture, .which may be read ily converted into an ice calk to prevent the wearer from-slipping when walking ouV ice,

and when lnot used .for this purpose. will serve as a protection tothe heel from wearing-out,

A is a ring or plate of iron .or steel, which is intended to be permanently fastened to the sole of the boot or shoe by' means -of :the four screws B BB B, placed at equal'distances apart. This notonly serves as a protecting plate to the heel, to preventV its wearing'out, but is intended also to' serve as a frame to' which the other parts are attached.

f Gis a sem'icircular spring-band of steel, each end of which is but at right angles toward the center o f the circle, thus forming anv axis ou which the band turns.. These endsv work in slots made to receive them in the ring A. One edge of the band-G isserrated .and the other smooth. When? thelhand is y turned 'so that it rests on the banket-fthe heel,

the serrated edge lis exposed, and" the 'tread of the foot causes it to take sharp hold of the ice; but when-the baud is turnediu the o-ppo-V site direction,'as shown in section in Fig. 3, the serrated edge is turned toward the foot and the smooth edge is exposed. The advantage of this arrangement is readily seen.

AWhen a person is obliged to walk on ice or slipperyv sidewalks, the serrated edge is exposed, and he cnn-do so with safety; but when he arrives at his house thecalks become Worse than useless, for they would injure his oors and carpets; he has simply to reverse. the band, and his heel becomes smooth and harm less. Thehand C Vis -so made and arranged ,that whenthrown' to itsseat either forward or baclirv'vard,.it issp'rung lonto the ringe.l by the Aforce ofthe person treading upon it, and holds itself firmly in place. New,l in order that the wearer may'v without trouble ord-ifi-- l culty reverse the band 0, I have provided the double sliding wedge D. By'kieking with the.

foot so as to bring one end of this wedge -'against the door step or scrapcrit drives the other'end of this wedge against the band in such a' manner .as to loosen it, so that it can easil beturned in the opposite direction by the oot alone, thus avoiding all necessity of touching it with the hand.

Ido not limit my claim to the particuar i for l of wedge as herein shown, but extend it toyanyjother substantially the same.

What I claim as my invention, and desire to secure by Letters Patent, is l The double sliding wedgerD, used for the and in the manner as herein set purposes forth.
